Part Number: DRV10987

Dear, Sir.

My customer would like to put the digital transistor on PG output pin.

The current will be around 1mA.

Is it no problem on this kind of usage because the internal configuration will

be push-pull?

Best Regards,

when you say PG pin, do you mean FG pin?

If so, I think 1mA should be fine because the datasheet electrical spec FG voltages are done at test condition Io = 5mA as shown below, but let me confirm. I need to confirm that the Io is the current coming out of the FG pin.

Dear, Sanmesh-san.

Sorry to ask you so many things.
They will start the design within short time, so many questions are coming.

I am hoping to get your help, one more time.

Best Regards,

I didnt manage to confirm today, so let me get back to you on this on tuesday when people come back from holiday, but I believe 1mA should be fine.
